From: Risk-sensitive foraging and the evolution of cooperative breeding and reproductive skew
Reproductive output of groups with and without skew. Influence of the cost of reproduction (reproduction threshold, s), the reproductive potential of individuals (half saturation constant, h), and the standard deviation of individual foraging success (σ) on the relative reproductive success of groups (N = 2) without reproductive skew (a, σ = 0.5; c, σ = 0.2) and with reproductive skew (b, σ = 0.5; d, σ = 0.2). Integration of equations 3, 6 and 7 for mean foraging success μ = 1.
